I have a 99' 115 merc that lost a vent screw and froze last winter pushing the bearing carrier (16) out. I replaced the carrier and now can't get it to shift right. I installed the prop shaft with the shift cam and throttle in the forward detent position. It will only shift into neutral when I put it into reverse. With the shifter in reverse I removed the prop shaft and the shift cam was in the reverse position. It's almost like the cam follower (7) is too short. Below is a schematic and a picture of the cam follower sitting in the shaft. I don't seem to be missing any parts but it looks like the follower might be short. Does anyone have experience with these models? It's much appreciated! Thank you.
